CAUTION
DANGER
Do not touch the rotating part of the motor
while operating.
The failure could result in injuries.
Ground the earth of the brushless motor and
brushless amplifier.
The failure could result
in electric shocks.
Do not expose the cables to sharp objects,
excessive pressing or pinching forces, and
heavy loads.
The failure could result in electric
shocks, damages, or malfunction.
Install an external emergency stop device
to shut down the main power source in any
emergency.
The failure could result in electric shocks,
injuries, fire, damages or malfunction.
Do not place inflammable matter near the motor,
amplifier and external regenerative resistor.
The failure could result in fire.
Mount the brushless
motor, brushless
amplifier and external regenerative resistor on
incombustible material such as metal.
The failure could result
in electric shocks, injuries, or fire.
Arrange the phase sequense of the motor and
wiring of the CS sensor.
The failure could result
in injuries, damages, or malfunction.
Do not climb or stand on the brushless
equipment.
The failure could result in electric shocks,
injuries, damages, or malfunction.
Make sure to secure the safety after the
earthquake.
The failure could result
in electric shocks, injuries, or fire.
Do not approach to the equipment after
recovery from the power failure because they
may restart suddenly.
The failure could result in injuries.
Do not hold the cables or motor shaft when
transporting the motor.
The failure could result in injuries.
Do not touch the motor, amplifier, and external
regenerative resistor, since they become hot.
The failure could result in burns.
An over-current protection, earth leakage
breaker, over temperature protecter and
emergency stop device must be installed.
The failure could result
in electric shocks, injuries, or fire.
Transportation, wiring and checking must
be performed with power source turned off
and after making sure that there is no risk of
electric shock.
The failure could result
in electric shocks or injuries.
Do not subject the product to water, corrosive
or flammable gases, and combustibles.
The failure could result in fire.
Install the product properly to avoid personal
accidents or fire in case of an earthquake.
The failure could result
in electric shocks, injuries, or fire.
Do not connect the cable (U, V and W) of the
brushless motor directly to the commercial
power source.
The failure could result
in fire, malfunction or damage.
Do not put your hands in the brushless
amplifier.
The failure could result in burns,
or electric shocks.
Only persons who are trained and qualified
to work with or on electrical equipment are
permitted to operate or maintain this equipment.
The failure could result
in electric shocks.
Do not drive the motor from the external power.
The failure could result in fire.
Never start and stop the motor by magnet
contactor which is provide on the main line.
The failure could result in damages.
